Claims.

The present invention relates to operating tables, particularly orthopaedicv operating tables, and has for its object to provide a new and improved operating table of simple and compact constructiomand capable of being collapsed to a small bulk for ready transport. Theparticular construction adapted to secure the collapsibility of the table, also permits adjustment of certain planes thereof so as to permit of a better and more convenient accommodation of the patient in certain orthopaedic operations.

A further feature-of the present invention, intimately connected with the desirable compactness aforementioned, is the provision of oriented apertures in two superimposed planes of the body portion of the novel table, whereby a plurality of accessory rod-like or tubular members may be detachably secured to the table in inclined or upright positions, said members being adjustable for height and being adapted to have instrumentalities of various kinds as for example pulley blocks, attached thereto.

Another feature of the novel table according to the present invention, lies in the fact thatthe body portion thereof comprises a top or table portion rigidly connected in spaced relation to a bottom or floor portion to form an open-sided box like structure to one end of which is slidably secured an auxiliary frame adapted to slide lengthwise of said structure and having slidably secured to it an renvelope having an upper surface adapted to act as an auxiliary table or extension and sides adapted, in the collapsed position of the novel table, to embrace the sides of said structure and enclose same, whereby the table proper is protected during transit, and is likewise converted into a closed receptacle in which accessories, instruments, lthe aforesaid members and the like may be packed.

'I'hese and other objects and advantages of the present invention will become apparent in the course ofthe following detailed description of a preferred embodiment thereof.

In the drawings:

Fig. 1 is a side elevation of an improvedoperating table according to the present invention.

Fig. 2 is a plan view of the table of Fig. 1 with the envelope member removed.

Fig. 3 is a section on the line lII--III of Fig. 2. Fig. 4 is a transverse sectional view of part of the body portion, and Fig. 5 is a transverse sectional View of the envelope.

With reference to the drawings, the novel orthopaedic operating table according to the present invention,k comprises a body portion; l0 consisting of an upper or table member |2`Arigidly connected `in spaced relation to a composite floor or lower member I4, by short hollow columns i6, i8, said columns I6 being open at the top as shown yat inFig. 2, to receive detachable accessory tubular members (not shown) and at thebottom detachably to receive tubular leg members 22. Tying said columns I6 and I8 together, "and assisting in giving rigidity kto the body assembly as well as `serving to support the table and oor members respectively, are upper and lower frame members 24 and 26 of angle section, the longitudinal members 28 and 36 of which have a pluvrality of'apertures 32adapted to receive acces-A soryrtubular members when it is necesary to place these'transversely of the table.

The upperor table member' l2 has its corners cut away as shown at 34 Fig. 2, to allow of access toY the upper open ends 2,0 of the columns I6. Said table member l2 has also a plurality of oriented apertures some of which, as for example the aperture 36 centrally disposed near `the end of lthe, table member remote from the cut away corners, pass normally through the table member, while others,l as for example the pair of apertures 38 symmetrically disposed in the neighborhood of the cut awaycorners, are cut at anangle to the normal such that they vslant downwardly and towardsthe opposite end of the table member, vand others, as for example the,

three apertures 40,42 and k44 spaced .along the center line of the table member, and two pairs 46,' 48 of 'apertures disposed symmetrically about said center line and near the longitudinal edges of the table member, slope in the reverse directionandstill others such as the apertures 5U and 52 "which are disposed in pairs alined with the pairs 45 and 48, the pair 50 coming between pair 46 and the columns I6 and the pair 52 lying be`` vtween, pairs 46 and 48, slope inwardly and downwardly crosswise of the table member. In the example shown" twol more pairs of apertures are provided in the table member, one of which, 54, is located near the corners remote from the cut away corners 34 vand the other, 56 of which is arranged lsymmetrically about central aperture 44. y f

The pair of apertures 54 is circular in crosssection as are all the other apertures in the table member so far particularly described, and said apertures 54 slope downwardly and inwardly in a direction approximately diagonal of the table member. The remaining pair 56, are'inthe shape of truncated rectangular pyramids with the larger end in the upper surface of said table member and the longitudinal center line normal to the table member. Some of the apertures, as for instance, apertures 4i) and 36, may have crossing them a recess 58, @S0 adapted to receive a pin (not shown) passing through said accessory tubular members or standards, to limit the penetration thereof through the body portion I0.

In Fig. 3 one accessory tubular member is shown in dotted lines at passing through aperture 42 of the table member and another opening to be hereinafter described. It will be observed that said tubular member E2 has transverse perforations 64 adapted to permit of the passing there-` through of the aforesaid pins.

Such accessory tubular member may be utilized, for example, to sustain a support havinga slot therein, into which a plate is adapted` to be'v |00, spaced from said central bar 98 to form gaps |02 for a purpose to be hereinafter explained. The ends of the shorter bars |00 remote from the central bar 98 are substantially in alinement with the inside edges of the longitudinal members 84 of the frame 80. The object of this arrangement will become clear at a later stage of this description.

yMounted on the auxiliary frame 86 is an envelope or housing |04, having sides |06, a top |08 and having its end remote from the body portion l0 closed by an end wall ||0. The housl ing |04 is therefore open at the bottom and at beneath the longitudinal members 84 o'f frame introduced and secured, said plate being-useable as a rigid support for a foot, and being adapted to have a bandage, dressing said foot, also wound round said plate, particularly when the foot has to be put in plaster, whereby `cracking of said plaster owing to movements of said foot is avoided, and more especially', said foot -is firmlyv held during the whole time necessary, and it lis also'possible to disengage the foot from the said plate without breaking the plaster, as for instance for inspection.

Referring now to Figs. 1 and 3, the floor member I4 comprises perforated cross members 66, 68 and. 10, the perforations of which are alined with the perforations of the table member. In Fig. 3 only the perforations 12, 'i4 and T6 corresponding respectively to the apertures 40, 42 and 44 in the table member, areshow-n, but itis believed that the general idea of the lay-out will be clear from the foregoing to those skilled in the art. f

,The floor member I4 further comprises ller members 'I8 which may be imperforate and of thinner material than the cross members 66, 68

and I, since said filler members are intended only to complete the flooring, whereas the cross members 66, 63 and 'I0 likewise serve as .intermediate ties for the lower frame member 2S.

Parallel with the free, or lower, marginal v,portion of the upper longitudinal members 28 of the upper vframe 24, is an L section guide member 80,

which terminates at the vend thereof remote `from to allow of the'insertion of a xing pin 90 (Fig.l

1) when the auxiliary frame is in fully extended position as shown in said Fig. 1, to prevent accidental'telescoping of said auxiliary frame into the body portion I0. The end 82 of the frame 80 remote from the heads 88, is likewise of angle section and has pending therefrom a pair of tubular feet 04, adapted to receive detachably at their free ends extension members 9G, which are added when the tubular leg members 22 are inserted in the columnsl I6, I8 of the body portion I0, so that the frame 86 may be supported in parallel relationship to said table member I2.

The upper side of the member 92 has-secured to it a central bar 90 and two shorterouter bars 86, and thus limits upward movement of the open end of said housing, Downward movement of the housing is limited by longitudinal fins H4 projecting inwardly from the side walls |06 of the housing and adapted 'to rest slidingly on the longitudinal members 84 of frame 86. The ends of said: fins H4 nearest the open end of the housing |04, are bent up to form turning shoes H6 and in the proximity of said turning shoes, the fins II 4 are provided with claws ||8 which extend downwardly past the inner edges of the longitudinal members 84 and limit lateral and upward movement of the housing with respect to the frame 85. The inner edges of the fins H4 are substantially flush with the inner edges of the longitudinal lmembers 84 so that they slidingly contact the outer ends of the shorter bars |00 aforementioned.

As bestv seen in Fig. 2, the longitudinal members 84 of frame 85 are recessed at their junction with the end member 02 to form slots |20 Wherethrough the claws H8 are adapted to be lifted when the housing |104 has been slid away from the body portion as far as possible, that is until the claws H8 abut against the end member 92. The claws H3 are liftedthrough said slots by raising the closed Aend I-I0 of the housing 04 during which movement vthe open end of the housing turns on. the turning shoes H6 which support the weight of said open end by bearing on the Vlongitudinal members 04. When the lclaws H8 have been lifted `through said slots I 20, the housing may be slid ifurther away from the body portion I0, while riding on the turning shoes H6, until said turning shoes themselves are clear of the end member 92. lThe angle of the turning shoes I IG with respect to the fins I4 is such that when the turning shoes I I6 are 'in engagement with the longitudinal members 84, the upper portion of the open end of the housing is valmost touching the longitudinal members, so that when the housing has been slid away from the body portion I0 until the turning shoes H6 clear the end member 92 as explainedabove, the open end of the housing will drop so small an amount as-not to cause a damaging bumping thereof against the longitudinal members 84.

When in the circumstances just explained, the closed end of the housing |04 is lowered, the turning .shoes H6 and the hns I |4 may be passed below the longitudinal members 84 whereby the housing is dropped Afrom theaposition shown in Fig. l and the top |08 is brought in-close proximity to said longitudinal members.

Owing to the fact that said longitudinal mem-v bers or arms 84 are positioned with respect to the table member I2 to be slid therebeneath, it is necessary tov provide means for maintaining the top |08 of the housing,'when in itsl lowered posi-V tion level with said table member, since said top is then intended to acrl as an extension of said table member. Said level maintaining means comprise an upper cross member |22 secured to the member 02 of frame 86 thereby providing a second levelling support for said top in any position of the housing relatively to said body portion l0.

The depth of the housing |04 is such that, in its lowered position, and with the frame 80 telescoped into the body portion as previously explained, the housing may just be slid over said body'portion .to enclose same, the top |08 lying over and protecting the table member I2, the sides |06 covering the otherwise open'sides of the body portion l and the end ||0 closing the corresponding end of said body portion, the opposite end of which may conveniently be provided with a hinged panel indicated in dotted lines at |26 in Fig. 1 so as to complete the closure. When such panel is fitted, abutment members |28 therefore may be provided between the table and the oor members of the body portion as shown in Figs. l-and 4. When the table is in collapsed position two detachable wooden plane members are located between the table member |2 and the top |08.

From the foregoing it will be seen that by the present invention there has been provided an operating table which can be collapsed into a very compact unit, which, in addition to being readily transportable and particularly suitable for transport where the'space factor is a very important consideration, as for example in aircraft, will also serve to contain all the necessary accessories, instrumentalities, instruments, bandages, weights and the like, and can rapidly be set up for use. It also permits of the locating of such accessories as standards, limb supports, tensioning means and the like in the proper positions requisite for most orthopaedic and also some surgical purposes thereby permitting the duplication in the field of a fully equipped modern theater table, with the consequentl advantage to the patient and to the surgeon called on to perform emergency operations at places remote from hospitals. Apart from this use of the novel table, it has proved to be of great utility as part of the equipment of an ordinary operating theater, since the readiness with which the ancillary apparatus can be positioned therein and secured thereto, and the fact that the housing top forms an additional surface which can be adjusted lengthwise of the table as a whole and which has an upper and a lower eiective position, together with the compactness and relatively low cost of the novel table, make it useable not only as a means for holding a patient in a particular position for an extended period of time, as in the treatment of fractures, but also as an actual operating table.
